PSMNR51-25YLH is Nexperia’s lowest RDS(on) MOSFET
Described as its lowest ever RDS(on) device, the PSMNR51-25YLH is a power MOSFET which it claims sets a new standard of 0.57mOhm at 25V. It uses Nexperia’s NextPowerS3 technology which does not compromise parameters such as maximum drain current (ID(max)), safe operating area (SOA) or gate charge QG, says the company.
Very low RDS(on) devices are required in many applications such as ORing, hot-swap operation, synchronous rectification, motor control and battery protection, to reduce I²R losses and increase efficiency. However, some competing devices with similar RDS(on) values suffer from reduced SOA – a measure of the ruggedness of the MOSFET – and reduced ID(max)) ratings due to shrinking cell-pitches. Nexperia’s PSMNR51-25YLH MOSFET offers a maximum drain current rating up to 380A. This parameter is especially important in motor control applications where motor-stall can result in very high current surges for short periods, which the MOSFET must withstand for safe and reliable operation. Some competitors provide only computed ID(max) whereas Nexperia demonstrates continuous current capability up to 380Amps, says the company.
The device is packaged in LFPAK56, Nexperia’s 5.0 x 6.0mm Power-SO8 compatible package. This has a copper-clip construction which absorbs thermal stresses, increasing quality and reliability, says Nexperia.
Typical applications include: battery protection, brushless DC (BLDC) motor control (full bridge, three-phase topologies), server power for ORing, hotswap operation and synchronous rectification.
Nexperia produces discrete and MOSFET components and analogue and logic ICs that meet the stringent standards set by the automotive industry. It produces over 90 billion semiconductors annually and believes its products are in industry-leading small packages that save valuable energy and space.
Nexperia has over 11,000 employees across Asia, Europe and the USA, an extensive IP portfolio and is certified to IATF 16949, ISO 9001, ISO 14001 and OHSAS 18001.
